We all believe with the heart and confess with the mouth that there is one only simple and spiritual Being, which we call God; and that He is eternal, incomprehensible, invisible, immutable, infinite, almighty, perfectly wise, just, good, and the overflowing fountain of all good.
We know Him by two means: First, by the creation, preservation, and government of the universe; which is before our eyes as a most elegant book, wherein all creatures, great and small, are as so many characters leading us to see clearly the invisible things of God, even his everlasting power and divinity, as the apostle Paul says (Romans 1:20). All which things are sufficient to convince men and leave them without excuse. Second, He makes Himself more clearly and fully known to us by His holy and divine Word, that is to say, as far as is necessary for us to know in this life, to His glory and our salvation.
We confess that this Word of God was not sent nor delivered by the will of man, but that men spake from God, being moved by the Holy Spirit, as the apostle Peter says; and that afterwards God, from a special care which He has for us and our salvation, commanded His servants, the prophets and apostles, to commit His revealed word to writing; and He Himself wrote with His own finger the two tables of the law. Therefore we call such writings holy and divine Scriptures.
We believe that the Holy Scriptures are contained in two books, namely, the Old and the New Testament, which are canonical, against which nothing can be alleged. These are thus named in the Church of God.
The books of the Old Testament are the five books of Moses, to wit: Genesis, Exodus, Leviticus, Numbers, Deuteronomy; the book of Joshua, Judges, Ruth, the two books of Samuel, the two of the Kings, two books of the Chronicles, commonly called Paralipomenon, the first of Ezra, Nehemiah, Esther; Job, the Psalms of David, the three books of Solomon, namely, the Proverbs, Ecclesiastes, and the Song of Songs; the four great prophets, Isaiah, Jeremiah, [Lamentations,] Ezekiel, and Daniel; and the twelve lesser prophets, namely, Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, and Malachi.
Those of the New Testament are the four evangelists, to wit: Matthew, Mark, Luke, and John; the Acts of the Apostles; the fourteen epistles of the apostle Paul, namely, one to the Romans, two to the Corinthians, one to the Galatians, one to the Ephesians, one to the Philippians, one to the Colossians, two to the Thessalonians, two to Timothy, one to Titus, one to Philemon, and one to Hebrews; the seven epistles of the other apostles, namely, one of James, two of Peter, three of John, one of Jude; and the Revelation of the apostle John.
We receive all these books, and these only, as holy and canonical, for the regulation, foundation, and confirmation of our faith; believing without any doubt all things contained in them, not so much because the Church receives and approves them as such, but more especially because the Holy Spirit witnesses in our hearts that they are from God, and also because they carry the evidence thereof in themselves. For the very blind are able to perceive that the things foretold in them are being fulfilled.
